between 2 nodes in any Ethernet collision domain on the network, not only for the network cards of the 2 nodes, but also for the network cards of any node on the same Ethernet conflict domain. Therefore, if you listen to any node on the Access Ethernet conflict domain, you can capture all the packets that occur on this Ethernet, unpack and analyze them, and stea

terminal devices they use to log on to the enterprise network. Therefore, enterprises face a higher risk of malicious program intrusion. Network Access Security Control is specially designed for the current IT internal control to ensure effective security control for all devices accessing

continuously, the server replies to the confirmation packet, and waits for the customer to confirm, because the source address does not exist,The server needs to be continuously re-sent until timeout, these forged SYN packets will take a long time to occupy the disconnected queue, the normal SYN request is discarded,The target system is slow to operate, causing network congestion and even system paralysis in severe cases.Which certificate should be t

used to solve the problem. 2.1.2 network Isolation Technology The network is segmented and isolated based on different functional, confidentiality, and security levels, which has many benefits to the security of the entire network. A more refined

Currently, the network security market is dominated by firewall, IDS/IPS, network switches, SOC, and other application-layer network security products. In addition to the above products, Wangyu Shenzhou Technology Beijing) Co., Ltd, introducing a new kernel reinforcement con

installed within 300 meters can be automatically added to the Local Wireless LAN network, so that the local wireless LAN is prone to illegal attacks. At present, the formation of low-grade Wireless LAN has the following security disadvantages: Disadvantages of wireless network security 1. Imperfect

Three major network security categories: Microsoft's network access protection and Microsoft's network access protection. How to recover it becomes the problem of Microsoft's network access protection, the steps of network

WEP, so a basic principle is to set the WEP key as high as possible. Regular replacement keys It is not always necessary for all environments to change the key every week, but you should consider changing the key at least once a quarter. As time progresses, a wireless network that never replaces a

the Notification Packages string under the LSA key value and add the value passfilt. dll. This string value must be added to all domain controllers of the company. At the same time, you also use the passprop.exe program to make passfilt. dll take effect. Password Security in UNIX In UNIX, the encrypted password information is stored in a file, usually/etc/passwd. Maintaining the

Comments: The following describes the Common Omissions in the TEN network security settings, no matter how much effort we make, end users, or even enterprise IT departments, security omissions that are easily corrected will still be ignored. This article will discuss with you 10 Security omissions that can be avoided a

On the one hand, network security is ensured by encryption. The following describes common wireless network encryption methods. Through the introduction of these encryption methods, you can learn how to set up security and what security vulnerabilities are. Although the name

encryption. Wireless access points can be configured to broadcast Access Point SSID and domain name, which is usually not required. By disabling broadcast, you can largely stop disclosing your network to the outside world. Yes, the SSID is transmitted when the wireless node is connected to the wireless network, but it is not common in comparison. The SSID should be set to not describe the enterprise inform

WirelessNetworkSecurityAlthough the name seems to be a security option for wired networks, this is not the case. The WEP standard has been created in the early stages of wireless networks and is designed to become a necessary security protection layer for WLAN in Wireless LAN. However, the performance of WEP is undoubtedly disappointing. It is rooted in design defects. In WEP systems, data transmitted over

The NGN access network technology is currently one of the most important technologies to ensure network security. Many people may not know the characteristics and applications of the NGN access network technology. It does not matter. After reading this article, you will certainly have a lot of GAINS, I hope this articl

Find a wireless network Finding a wireless network is the first step in an attack, where two common tools are recommended: 1, Network Stumbler a.k.a NetStumbler. This windows-based tool makes it very easy to find radio signals that are broadcast in a range, and to determine which signals or noise information can be used for site measurements. 2, Kismet. A

nginx !! The above is a simple defense model. The following describes various functions: 1. The core scheduling node of the Headquarters is responsible for modifying the DNS server records, and adding real ip addresses to the website based on different IP addresses and different background cdn security nodes, and synchronize the final settings to the nginx of each local node. 2. The local node nginx is responsible for the direction proxy of the web

No matter how much effort we make, end users and even the IT department of the enterprise still ignore the security lapses that could have been easily corrected. This article will discuss 10 safety lapses that can be avoided and tell you how to correct this negligence. 1: Use a weak password There was a time when some people were smart to use "password" as a password to fool hackers and other malicious elements who tried to guess the password. After

what intruders look like. Therefore, your MAC list contains three types of visitors: first, friendly visitors exist in the visitor list; second, no visitors in the list and unintentional visitors; third, it is not in the list, but you can be sure that you have never invited yourself and tried to break in. If they will try to break in, they can now be confirmed immediately. In short, if you detect wireless networks and find that visitors not on the MAC list attempt to initiate multiple accesses,
